I l INVENTOR ATTORNEY Patented as. 19, 1932 UNITED STATES ALFRED GICILIONI, on nno rvinnn, vrnnnsynvnua DRILLING moraine l Application filed September 19 1928. Serial No; 306,900.

This invention relates to improvements in drilling apparatus and has especial reference to means for feeding a drill to its work.

An object of the present invention is the provision of a drill which is especially'adapted for mining operations, which includes a jack having means whereby the drill may be adjustably positioned to properly direct the drilling operation, means being provided for readily arranging the jack structure which supports the tool operating unit of the drill so that the same may be arranged in the most advantageous position.

Another object of the invention is the provision of means mounted upon the jack for yieldingly forcing the tool to the work, and for adjusting the tool forcing means as desired. p

With the above and other objects in view,

the invention further includesthe following a novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

5 In the drawings 3 1 Figure lisa. side view of a drill supporting jack constructed in accordance with the invention, the main post being broken away.

Figure 2 is an end view.

. Figure 3 is a horizontal sectional view taken substantially on the line 3-3 of Figure 2. v

Figure 4 is an enlarged section on the line 4-4: of Figure 1.

Figure 5 is a similarview on the line 5-5 of Figure 2.

Referring to the drawings in detail wherein like characters of reference denotecorresponding parts, the referencecharacter 10 indicates themain post of the jack which may be of tubulanconstruction. A threaded extension '12on the lower end of-the post is provided with a pointed foot 13 to engage the floor, so that the post may be supported between the floor and ceiling and adjusted to the desired height. The extension 12 is provided with an opening for the reception with the partlcular character of the work. 7

of abar 14; to facilitate adjustment.

Mounted uponthe post 10 is a horizontally disposed radially arranged ar1n15 and the inner end of this arm carries a clamp 16 by means of which the arm is secured to the post. The clamp 16 is rotatable and slidable upon the rpost and in order to hold it against accidental movement, a screw 17 extends through the clamp and engages within any one of a number of spaced openings 18 provided in the post. The Vertical or horizontal positionof the radialarm 15.may thus be regulated. 5 Slidinglyl mounted upon the arm. 15 is a carrier block 19. This block may be adjusted longitudinally of the arm 15 and held in adjusted position by clamping. nuts 20. Carried by='the block 19 .is a guide arm 21 and slidingly mounted uponthis arm is a carriage 22 which supports a tool operating unit 23. This unit carries a drill 24; .whose shank isxfmovable in a guide 25 at the outer endof the arm 21. A suitable operating agent may be fed to the drill unit 23 through apipe 26 which is controlled by. a; valve 27 awThefinner end of the arm 21 supports a .block 28 and pivotally mounted upon this blockasshown at 29 is the inner end of an actuating .or pusher arm 30. The outer curved end 30 of this arm has pivotal connection 31 with the outer end of arod 32, and the inner end ofthis rod is pivotally connected as at 33to the carriage 22. This carriage is freely slidable along the arm 21 and for this purpose is provided with antifriction rollers 33 The actuating arm 30 is adapted to yieldingly force the carriage outward so as to fit the drill to itswork, and for this purpose there is provided a spring 8 1 which is positioned upon one side of the arm 21. The inner end of this spring is secured to an arm 28 as shown at 35. This arm 28 is fixedly secured to the block 28. i

Any suitable means may be provided for securing the spring to the arm 28, such as a pin removably engaged in any one of a number of spaced openings 36 provided in the arm. The position of the inner end of the In.

spring may thus be adjusted with respect to the pivot pin 29 of the arm 30 in accordance A turnbuckle 37 is arranged between the springand arm 28, while the end of the spring is secured to the curved end of the arm 30 as shown at 38.

It will be apparent from the foregoing description and accompanying drawings that when the drill is in use the action of the spring 34 will be to force the carriage out- Ward, so that the drill Will be automatically fed tothe. Work as the drill operation progresses.

If desired, a Weight lO may be provided assist the spring 34: initswork. This Weight is secured at the outer end of a cablev 41 and the latter is turned over horizontally spaced pulleys 42 Which are supported at the upper end of the post 10. The cable also passes around a pulley l'3 spaced downward from the pulleys 42 and: supported by the post 10 and hasits other endiatta'cheditothe:pivot.3l

which connects the.=arnr 30-and the rod 32'.

Theinvention, is susceptible: of various changesin its form proportions and minor details of. construction and the: right isherein. reserved tomake such. changes as properly fall within: the scope of. the appended claim.

Having described: the: invention What is claimed: is z.

In. a devicev oi thecharacter described,. a guide arm means to support said. arm, a. carriage movable along the guide arm,. a tool operating unit securedto the carriage, a tool extending from the said, unit,. a pusher arm pivot-ally mounted upon the inner end of the guide arm, a rod: having oneend. pivotal ly secured; to the inner end. of the pusher arm, meansto secure. the other end of thelrod to the carriage, whereby relative movement of the pusher arm; and. rod: will move the earriage longitudinally of: the guide: arm, and a spring having one end. anchored fixedly with respect to the guide. arm and its other end secured to the pusher arm to yieldingly force the carriage outward.
